Purpose

To estimate the prevalence of patient-reported midday fogging and to identify risk factors for midday fogging.

Method

A multicenter, cross-sectional study was conducted with an electronic survey that was distributed to scleral lens practitioners. The survey asked them to describe their most recently examined established scleral lens patient. Respondents provided data about patient-reported midday fogging, patient demographic characteristics, indication for lens wear, lens-wearing schedule, lens design, and care products.

Results

Of the 248 survey respondents who indicated whether their patients had midday fogging, 64 (25.8 %) had patients who self-reported such issues. Midday fogging was not associated with demographic characteristics (age, sex, race/ethnicity), indications for scleral lens wear, mean lens diameter (P = .30), haptic design (P = .29), use of a daily cleaner (P = .12), disinfection/storage solution used (P = .71), or filling solution (P = .65). Patients who reported midday fogging more commonly reported redness or irritation associated with scleral lens wear compared with those who did not experience midday fogging (P = .03).

Conclusions

Prevalence of midday fogging in this study was similar to previously reported rates. No specific lens design or care product was associated with patient-reported midday fogging. If inflammatory mediators are elevated in the postlens fluid reservoir of patients with midday fogging, as previously described, the redness or irritation associated with scleral lens wear suggests that ocular surface inflammation may be contributing to this phenomenon.

与患者报告的固定巩膜镜片配戴者正午起雾相关的因素

目的

估计患者报告的中午起雾的流行率并确定中午起雾的风险因素。

方法

一项多中心、横断面研究通过分发给巩膜镜片从业者的电子调查进行。调查要求他们描述他们最近检查过的巩膜镜患者。受访者提供了有关患者报告的中午起雾、患者人口统计特征、镜片佩戴适应症、镜片佩戴时间表、镜片设计和护理产品的数据。

结果

在表示他们的患者是否有中午雾气的 248 名调查受访者中，64 名 (25.8%) 的患者自我报告了此类问题。中午起雾与人口统计学特征（年龄、性别、种族/民族）、巩膜镜片佩戴适应症、平均镜片直径（P = .30）、触觉设计（P = .29）、使用日常清洁剂（P = .12)、使用的消毒/储存溶液 ( P = .71) 或填充溶液 ( P = .65)。与没有经历正午起雾的患者相比，报告正午起雾的患者更常报告与佩戴巩膜镜相关的发红或刺激 ( P = .03)。

结论

本研究中中午起雾的流行率与先前报告的比率相似。没有特定的镜片设计或护理产品与患者报告的中午起雾有关。如果炎症介质在中午起雾的患者的晶状体后液库中升高，如前所述，与巩膜镜片佩戴相关的发红或刺激表明眼表炎症可能是导致这种现象的原因。
